Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a light fixture for two-wheeled vehicles such as motorcycles, which is attached to the rear fender and used as a tail and license lamp.

(Prior Art) As this type of lamp, for example, one having a structure disclosed in Japanese Utility Model Application Publication No. 52-7175 is known. In this known light fixture, a mounting stay with a predetermined shape is provided as part of the vehicle body, for example, on the fender, and the light fixture is attached to the stay, rather than being attached directly to the fender. It can be installed with it separated and protruding. in short,
The lamp itself does not need to be modified to fit the fender, and its structure is such that all of the light from the light source is extracted to the outside.

Therefore, in the case of a conventional lamp, a mounting stay must be used and must be positioned in a protruding state.

(Problems to be Solved by the Invention) The present invention eliminates the need for the stays used in conventional lamp installations, reducing the number of parts. This is an attempt to solve the problem that if the degree of protrusion is significant, it becomes a nuisance in various aspects.

(Means for solving the problem) A specific configuration for solving the above problem is to form the lower surface of the lamp obliquely to match the shape of the upper surface of the fender so that it can be directly attached to the fender of a motorcycle. , an inner lens is provided in a range corresponding to the lower part of the reflector lost due to the formation of the oblique shape, and the inner lens is attached to the reflector via a mounting member so that it can be disposed on the outer lens side. This light fixture for a two-wheeled vehicle has a structure in which the lower surface of the light fixture is formed diagonally and can be directly mounted, so that it does not require a mounting stay and does not protrude widely from the vehicle body, so it does not get in the way. By forming the lower surface obliquely, the reduction in the reflective surface of the reflector can be compensated for by using an inner lens, and the entire front surface of the lamp can emit light almost uniformly.

(Example) Next, the present invention will be explained in more detail with reference to the illustrated embodiment. Reference numeral 1 denotes a lamp, and the housing 2 of the lamp has a lower surface 3 formed obliquely along the upper surface of the fender 4, and the lower surface A mounting hole 5 for attaching to the fender 4 is provided in the fender 4. A lens 6 having a fisheye cut is attached to the front side of the housing 2, and a lens 7 for illuminating a license plate, which will be described later, is attached to the upper surface.

A support stay 8 is disposed inside the housing 2 along the lower surface 3, and the support stay is provided with a hole 8a corresponding to the mounting hole 5 and has a portion erected to hold a socket 9. A valve 10 is attached to the socket. In order to increase the illuminance of the lamp, a reflector 11 is provided to reflect the light from the bulb 10, and the lower part of the reflector 11 is short because the lower surface 3 of the housing 2 is formed obliquely. In other words, the reflector 11 should be formed in a state corresponding to the front lens 6, but since the lower surface 3 is formed obliquely, the lower portion 11a originally provided is lost. Incidentally, the valve 10 is provided with two filaments 10a and 10b.

An inner lens 12 is provided corresponding to this missing lower part 11a. This inner lens 12
An arcuate Fresnel cut 13 is provided corresponding to the reflector 11, and both ends of the inner lens are attached to the reflector 11 via attachment members 14. This inner lens 12 is disposed on the front lens 6 side.

When attaching the reflector 11 and the lens 6 to the housing 2, the attaching cylinder part 16 of the reflector 11 is brought into contact with the attaching boss part 15 provided on the housing 2, and the attaching boss part 17 of the lens 6 is brought into contact with the attaching boss part 15 provided on the housing 2. Attach by bringing them into contact and tightening them from the lens side with the bolts 18. In this case, the mounting tube 1
6 and the attachment boss portion 17 of the lens 6 are integrally connected in advance by ultrasonic welding, the reflector 11 and the lens 6 can be attached to the housing 2 at the same time. Furthermore, housing 2
Reflectors 19 are attached to both sides of the reflector.

For two-wheeled vehicles such as motorcycles, a license plate 20 is attached to the back side, but this license plate 20 is
It is attached close to the lamp 1 at the top. Then, the lamp 1 is attached to the inclined surface of the fender through the attachment hole 5 and the hole 8a of the stay 8 with a fastener such as a bolt.

(Function) The lamp of the present invention having the above structure can be directly attached to the fender 4, and by forming the lower surface 3 obliquely, a part of the lower part of the reflector 11 is lost. However, since the inner lens 12 corresponding to the lost part is provided, the bulb 10 (both filaments 10
Not only the direct light a from the rays 10a and 10b, but also the reflected light b reflected by the reflector 11 reaches the lens 6 on the front side. ' is guided to the lens 6 side as a parallel light beam, and the light is projected from the lens 6 to the outside. Therefore, lens 6
The entire surface of the light emits light, and even if a part of the light is missing a reflector, it can be compensated for.

(Effects of the invention) As explained above, the motorcycle lamp according to the invention has a structure in which the lower surface is formed diagonally along the upper surface of the fender, so it can be directly attached to the fender, and there is no need for a stay for installation. First, the installation work is simple, and in the installed state, it does not protrude significantly from the vehicle body, which not only does not get in the way, but also provides excellent installation stability.

Furthermore, by forming the lower surface diagonally to attach it directly to the fender, a part of the lower part of the reflector is lost, but by providing an inner lens to accommodate this lost part,
The light emitted outside the lens can be directed toward the lens by the inner lens, and as a result, the front lens of the lamp emits light over its entire surface, which also has the excellent effect of eliminating dark areas in some areas.
